SELVAGE-GUIDE FOR CLOTH-TENTERINCJ"` MACHINES.

SPECIFICATION forming part of Letters Patent No. 499,072, dated J' une6, 1893.

Application led January 2, 1892. Serial No. 416,306- CNO model-l T0 @ZZwhom t may concern.-

Be it known that I, JEEEMIAH CLARE Wrm.1d TLES, a citizen of the UnitedStates, residing at Kearney, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements in Selvage-Guides for Cloth-Tentering Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters of reference marked hereom which form a part of thisspecifica- Iion.

The object of this invention is to automatically guide cloth onto adrying ortentering machine whereby the said cloth is evenly andregularly disposed in said machine and prevented from Working laterallyout of proper relative position.

The invention consists in the improved guiding attachment and in thearrangements and combinations of parts thereof substantially as will behereinafter set forth and finally embodied in the clauses of the claim.

Referring to the accompanying drawings in which like letters indicatecorresponding parts in each of the several views, Figure 1 is a sideview of the improved attachment. Fig. 2 is a front view and Fig. 3 is asectional View of the same taken on lineocFig. l. Figs. 4, 5 and 6 areviews showing another variety of construction which is in many casespreferred, Fig. 4 being a view similar to Fig. 1, Fig. 5 a section ofthe same on line y, Fig. 4, and Fig. 6 an end view.

In said drawings, d indicates a bracket or xture of a tentering or clothdrying machine through which latter the cloth is caused to travel slowlyand be stretched and dried in any ordinary manner. To said ixture myimproved attachment is secured by a bolt, a', or by other suitablemeans. Of said attachment, b indicates a bed, which is preferablyslotted horizontally,` as at a2, to. receive the said bolt, a', andadmit of an adjustment of said bed as will be understood. The said bedis provided with arms b', b between which a carrier, c, is pivotallycentered.

The construction of thepivotal bearings is Shown clearly in Fig. 5,Where CZ, d, indicate hollow screws adjusted in said arms b', b',forming journal boxes or bearings, and c', c', are pivotal pins orscrews adjusted in the arms c2, c2, of the carrier and extendingoutwardly into ,the said hollow screws d, d, said pins having conicalextremities which engage corresponding bearings in said screws. Theconnecting bar or portion c3 of the carrier is eccentric in its relationto the pivotal centers and has a vertical vibration controlled by thecloth and a weight e. The said connecting portion c3 provides bearingsfor a fixed pivotal stud f, and a swing stud g, and on the former ofsaid studs are two friction wheels or pulleys 712', one of which islarger than the other and is loosely disposed thereon so as to revolvefreely with the cloth. The smaller wheel, h, is allowed but a limitedmovement, being held by a connecting rod, k, eccentrically attached tothe wheel or roller at one end and at its opposite end pivoted upon anarm Z, fixed to er forming part of the bed b. as will be understood uponexamination of Figs. 4 and G. When the cloth, as it works to one side inpassing to the tenter-ing machine, engages the said small wheel h, andcauses it to partly revolve or turn. Because of the connecting rod, thepivotal movement is very limited. The cloth drags on the roller and thelatter, because of its connection with the fixed arm Z, raises thepivotal carrier, so that the rollers assume a different angle and thecloth is forced to return to its proper relative position.

Upon the swinging stud, g, is arranged a roller, m, which pressesagainst the rollers h, 2', or the cloth'therebetween and tends toincrease the friction of the cloth upon the rollers 71,71. The pressureof the roll, fm, is regulated by a spring n and an adjusting screw obearing upon said spring. The pivotal stud, g, controlled by said springand in connection with its roll, m, regulates the pressure referred toand allows the wheel or pulley, m, to be turned or forced from thepulleys h, z', so that the cloth can be adjusted between or otherwisemanipulated. The spring n is secured on the pivotal stud and extendsinto engagement with the regulating or adjusting screw, o, which has itsbearings in the carrier, e, so that when the screw is turned in one wayor the other the tension of the spring and the pressure of the roller m,are either increased or diminished as will be apparent.

In lieu of the connecting rod, 7c, eccentrically secured to the roller,h, and at its opposite end to the fixture of the bed, I may employ othermeans to secure the desired change in the inclinations or positions ofthe rollers. For example, I may employ, in connection with the wheel, h,a series of cog or gear wheels shown in Figs. 1 and 2 at p, q, r, whichengage a rack, s, fastened upon the bed. In this' construction when theWheel, h, is turned, the swinging carrier and its wheels are caused tomove out of their normal positions and cause a return movement ot' thecloth as in case before described.

Other variations in construction ma e employed without departing fromthe spirit of the invention.

Having thus described the invention, what I claim as new is l. Theimproved regulating attachment for tentering machines herein described,in which is combined a stationary bed adapted to be secured upon saidtentering machine, a pivoted carrier, c, having rolls h, t', thereonarranged end to end, one of said rolls, h, being provided with aneccentric connection, c, with the bed, substantially as and for thepurposes set forth.

2. In combination with the bed b having arms b, b', a carrier pivotedbetween said arms, rolls h, and t', arranged end to end, a stud, f,extending from said lcarrier and carrying said rolls, the roll, t',being free to re` volve and the roll h having a limited movementpivotally being eccentrically connected to the bed, substantially as andfor the purposes set forth.

3. The combination with the tentering machine having lthe fixedattachment, b, of a swinging carrier having a stud,f, and rolls h, t',pivoted thereon, the roll, It, having a limited movement, beingconnected eccentrically to the said attachment b, substantially as andfor the purposes set forth.

4. The combination with the adjustable bed having arms b', b', a carriereccentrically suspended between said arms and provided with a pivotalstud, rolls 7L, t', arranged end to end on said stud, and the roll hhaving an eccentric connection with the bed substantially as and for thepurposes set forth.

5. The regulating attachment or guide herein described, in which arecombined with the bracket or fixture b, and pivotal carrier c, rolls711', arranged end to end, a roll m for pressing the cloth against saidrolls h, t', said rolls h, t', and m being carried by said carrier andsaid roll h having a connection with said bracket or fixture,substantially as and for the purposes set forth.

6. The improved regulating attachment or guide herein described in whichare combined with the fixture and pivotal carrier, rolls h,t`,

m, the last being a pressure roll pressing thecloth against the rolls h,t', disposed end to end, and connecting rod, la, eccentrically securedto said roll h and to said fixture substantially as and for the purposesset forth.

7. The improved automatic guide for tentering machines herein described,in which is combined an adjustable bed, b, having arms, b', a carrierarranged between said arms and movablein its relation thereto, rollsarranged on said carrier one of which is connected to said bed andadapted to draw the frame out of normal position substantially as setforth.

8. In combination, the adjustable bed, b, having arms b b,and screwbearingscl, d, a carrier, c, having arms c2, cwith pivotal pins c', c',working in said bearings CZ, a rigid studf and a swinging stud g,carried by the carrier, the rigid stud being provided with rolls h, i,the first of which is connected tothe bed and the latter free to revolveon said stud, a roller m arranged on the swinging stud and adapted topress the cloth onto said rollers h, t', and a spring n, and regulatingor adjusting screw o, all said parts being arranged and adapted tooperate substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this7th day of December, 1891.
